Table 2.
Total amount of carbon emitted by different grassland plant species during the complete 24 h drying process after cutting and relative percentage contribution by one oxygen containing VOCs (CxHYO), two oxygen containing VOCs (CxHYO2) and hydrocarbons (CxHY). Values represent means of four independent experiments replicated for each one of the three investigated plant species ± standard error of the mean. Different lowercase superscripts indicate significant differences between species at P < 0.05.
